You Don’t Want to See This Saleen Mustang Cop Car in Your Rearview Mirror

California’s Riverside Police Department took delivery of a 2016 Ford Mustang GT that had been handed to Steve Saleen’s shop and returned with a supercharged 5.0-liter V8 making roughly 730 horsepower and 600 lb-ft of torque, plus revised suspension, big brakes, and a rear wing under black-and-white livery. Built as a rolling memorial and community outreach tool rather than a patrol car, it is the modern extreme of a police Mustang tradition that dates back decades. Read on to find out how it came together.

You are doing sixty on a quiet stretch of Riverside County when a shape fills your rearview mirror, low, black-and-white, and closing fast. It does not look like the usual patrol sedan, and for good reason: underneath that livery sits a supercharged 5.0-liter V8 built not by Ford’s engineers but by one of the most famous Mustang tuners alive. Somewhere between a showroom Mustang GT and a 730-horsepower weapon, this car crossed a line most police fleets never approach. Riverside PD did not just want a fast car for the motor pool; they wanted a message. What convinced a California police department to put a supercar’s worth of power behind a badge, and who builds a cop car with a rear wing?

From Showroom Mustang GT to 730-Horsepower Enforcer

The car began life as an ordinary 2016 Ford Mustang GT before it was handed over to Steve Saleen’s outfit, Saleen Automotive. Saleen’s team fitted a supercharged 5.0-liter V8 that pushes output to roughly 730 horsepower and 600 lb-ft of torque, a massive jump from the stock GT’s 435 horsepower and 400 lb-ft. To handle that power, the car also received a fully revised suspension tuned for hard cornering and Saleen’s own big-brake package for serious stopping power. The result is a car that could run with genuine exotics while wearing a light bar, which is not a sentence that applies to many police vehicles.

Why Saleen Was the Right Name for the Job

Over the years, Saleen’s various companies have built some of the most epic Mustangs ever to leave a tuning shop, modified the Tesla Model S, and even produced a supercar of their own, the mid-engine S7. Steve Saleen built his reputation on the Mustang platform in the 1980s and never really left it, which makes his shop the natural choice for a department that wanted the fastest possible pony car. Handing the project to Saleen guaranteed that the finished car would carry real engineering credibility rather than just a bigger exhaust and a set of decals.

Dressed for Duty, Built for Show

Visually, the car wears black-and-white Riverside PD graphics over a reworked front fascia and a Saleen rear wing, with siren and external speaker hardware built into the design rather than bolted on as an afterthought. Inside, Saleen gauges sit alongside the department’s police electronics, and the emergency lighting is integrated into the cabin so the exterior keeps a cleaner profile. The attention to integration matters. Plenty of departments have slapped a light bar on a fast car, but few have gone to the trouble of making the police equipment look like it belongs on a tuner’s showpiece.

A Rolling Memorial, Not a Traffic Stop Machine

Reports at the time described the car as a rolling memorial to fallen officers rather than an everyday patrol vehicle, meaning it is far more likely to appear at community events, school visits, and promotional appearances than on routine traffic stops. That distinction matters for anyone worried about being chased by 730 horsepower. The car’s job is to draw a crowd and open a conversation, and a supercharged Saleen Mustang in police livery does that better than any brochure or booth. It is public relations with a supercharger.

The Long Tradition of the Police Muscle Car

Riverside was not the first department to put a performance car in uniform. Police-package Mustangs date back to the 1980s, when the California Highway Patrol ordered Fox-body 5.0 Mustangs as pursuit cars because the big sedans of the day could not keep up with the sports cars they were chasing. Those Special Service Package Mustangs became legends in their own right. The Saleen Riverside car is the modern extreme of that tradition, taking the idea of a police pony car and pushing it far past anything a fleet manager would have ordered from a catalog.

What 730 Horsepower Means in a Mustang

For context, the 2016 Mustang GT’s 435 horsepower was already enough to make it one of the quickest cars in its price range. Adding nearly 300 horsepower on top of that through supercharging transforms the character of the car entirely. Throttle response becomes instant, the rear tires struggle for grip in the lower gears, and the car pulls hard all the way to redline in a way a naturally aspirated GT simply cannot. Saleen’s suspension and brake upgrades exist precisely because that much power in a stock chassis would be more frightening than fun.

The Mustang GT Platform That Made It Possible

The sixth-generation Mustang that debuted for 2015 was the first with an independent rear suspension across the board, and that change is a big part of why a build like this works. Earlier Mustangs with solid rear axles could be a handful with big power, especially over rough pavement. The newer chassis gave tuners like Saleen a far more capable foundation, one that could put down serious horsepower while still cornering with composure. The Riverside car benefits from that platform directly; it is fast in a straight line but also tuned to handle, which is rare for a police car of any kind.

Community Policing With a Supercharger

There is a genuine strategy behind cars like this. A police department that wants to connect with younger residents and car enthusiasts has few better tools than a vehicle those people actually want to see up close. At a car show or a community event, the Saleen draws a line of people who might otherwise never speak to an officer, and every one of those conversations is the point. The horsepower is the hook, but the goal is the interaction that happens after someone walks over to look at the engine bay.

What It Costs to Build a Car Like This

A project of this scope is not something a police budget typically covers on its own. Cars of this type are usually built through partnerships, sponsorships, and donated work, with the tuner and suppliers contributing in exchange for the exposure. That arrangement is part of why the car functions as a memorial and promotional vehicle rather than a patrol unit; it exists because people chose to build it, not because a fleet manager requisitioned it. The result is a one-off that belongs to the community as much as to the department.

Why This Car Still Turns Heads

Years after it first appeared, the Riverside Saleen remains one of the more memorable police vehicles to come out of Southern California, and it is easy to see why. A black-and-white Mustang with a rear wing and a supercharger whine is an image that sticks, and it captures something about Southern California car culture that no sedan ever could. Whether it is parked at a show or rolling through a parade, the car does exactly what it was built to do. It makes people stop, look, and wonder what a 730-horsepower cop car is doing in their town.
